These reagents follow the DPD (N, N-diethyl-p-phenylenediamine) method to determine free chlorine concentration.\u003c\/p\u003e\n\u003cp\u003eFor determination of free chlorine,  the sample is first adjusted to a pH near 6.3. When the DPD reagent is added to a sample containing chlorine,  the reagent is immediately oxidized. The reaction between chlorine and the reagent causes a red colored complex to form; the greater the concentration,  the deeper the color. A color comparator cube is included for an accurate,  side-by-side,  visual analysis to determine free chlorine concentration. These reagents are designed to be used with samples that have an expected free chlorine range of 0.0 to 2.5 mg\/L (ppm) Cl\u003csub\u003e2\u003c\/sub\u003e.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI3831F-050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Free Chlorine Test Kit Replacement Reagents (50 tests) - HI3831F-050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e bottles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 50 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e DPD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI3831F-050\"\u003eFree Chlorine Test Kit Replacement Reagents (50 tests) - HI3831F-050\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871267914097,"sku":"HI3831F-050","price":1530.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3831f-050_1.jpg?v=1792645996","url":"https:\/\/hannainst.in\/products\/free-chlorine-test-kit-replacement-reagents-50-tests-hi3831f-050","provider":"hanna","version":"1.0","type":"link"}
